Relationships: Closely resembles I). (ü) kuntzei DUDA, especially in the shape of male and female genitalia, but differs from it in having less distinct clouds of crossveins, longer CJ-fringe, subapically broadest aedeagus (apically broadest in kuntzei, cf. Figs. 23-24), and much longer ultimate marginal and discal teeth of egg-guide (cf. Fig. 18). Drosophila (D.) metakuntzei sp. n. (Figs. 17. 21, 22) rf C
